The purpose of annealing for welding hardox 450 steel

The business department is mainly responsible for communicating with customers, from the manufacturing of steel plates, steel pipes and other products, knowing customers' needs and processing conditions, etc. within the time agreed with customers, the delivery time is short, the price is the most competitive, and the service is the best. Their responsibilities are to deal with customer consultation, solve customer problems, update production plans, and instruct the logistics department to deliver products to customers.

Q420B material is a low-alloy high-strength structural steel. welding Hardox 450 steel, Q420 is not high-strength steel, it is still low-carbon steel. Its tensile strength has been improved a bit. The tensile strength of Q235 steel is 235MPa, and the tensile strength of Q420B steel is 420MPa. Q420B low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good Cold forming performance and welding performance; has good corrosion resistance and certain wear resistance.

Alloy seamless pipe has good sealing performance and is often used in fluid transportation pipeline, such as pipelines for oil, water, natural gas, for which the steel pipe need to be buried underground for a long time. However, the alloy seamless pipe seldom causes leakage and the loss of resources can be reduced. The welding Hardox 450 steel, alloy seamless pipe is smooth in surface, and has small resistance to the fluid in the pipeline, so it will not block the pipeline. It can make the fluid pass through smoothly, so as to improve the efficiency of fluid transportation and speed up the transportation speed.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled welding Hardox 450 steel products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the welding Hardox 450 steel rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

We have a professional production team and high-quality production equipment, and we also have a great welding Hardox 450 steel advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the welding Hardox 450 steel production of high-quality steel plates, steel pipes and other products that meet customer requirements.

We had a wonderful trip in Phuket Island, Thailand. At the end of 2019, in order to thank employees for their hard work for a year and enrich their lives, our company organized a pleasant trip to Phuket Island, Thailand. The tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5 o'clock in the afternoon on the 22th December.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
